You've heard of Darwin's theory yes?
Is this real? Are you actually serious? Yes, I have heard of Darwin's theory of evolution. The preeminent explanation of our human history, ubiquitous in education around the world and in our culture. Yes, I have heard of this before. Who hasn't?
You're describing what happened out of evolution of language, but you're not answering why it happened. I said it already but I'll try to elaborate for you.
When a creature develops a mutation, that mutation (if significant) can negatively or positively impact their life. Typically, negative traits die off. If you have a mutation that gives you cancer within 4 years of being born, you tend not to have the chance to spread that gene.
Conversely, if you have a trait which is somehow productive for your life and environment ("fit" as is so often described), it tends to get passed on. Because all things being equal, if you have a slight advantage over the other creatures who don't have that useful mutation, you will produce on average more offspring through a generation. This is how positive mutations can evolve a species.
How does language give us an advantage over other humanoids that don't have language? What makes it beneficial to our environment?
Well for one thing it encourages social bonding. With complicated phrases we can convey our emotions better than grunting and waving our arms in the air. This creates a more cohesive social structure where a tribe (or whatever) is more likely to support each other, and therefore they perform better at "life" and produce more offspring than an uncohesive tribe.
But it's not just the social bonding, it's also the practical transfer of information. This is truly the most amazing feature of language. You can tell people how to do things instead of having to show them concrete behaviors contemporaneously. You can give people information for their own future scenarios. You can give them advice for what to do when you're not around. For example, "when the autumn arrives you ought to stock up on food so you can survive the winter" - even when you aren't there to do it for them. By teaching people how to do things through your words, we can build a stacking pyramid of learned behaviors. Language is mostly useful, because it helps to tell people how to do things right.
So in Squad, unless you're reporting a matter of fact ("enemy APC in the FOB"), usually you're telling people how to do something. Which is almost always triggered by someone not knowing how to do something. Like, not knowing how to be on the flag in play - so you tell them to get on the flag in play. That is 75% of comms. And the other 25% is reporting information.
Hence,
i've found that if everyone always did what was obvious and good, there would be very little to talk about in this world.
what's really funny here is you disputing my theory that most discussions are people correcting each other, by trying to correct me. in the total history of history together, it has 100% been arguing with one another. Thank you for personally proving my point.
